Edison was born in America. He is the first person in human history to apply for an invention patent by using a large number of laboratories to conduct research on production principles and electrical engineering, which has a far-reaching impact on the world. He had more than 2000 inventions in his life. His main achievements are the phonograph and the electric light, let's say the electric light. I met Edison through the electric light. If he hadn't invented the light bulb, our life wouldn't have become convenient.
Although he is a smart and powerful man, he also has a cruel side. At that time, Tesla also worked in Edison's company, but their opinions were divided. In order to suppress Tesla and prove that he was right, he did not hesitate to hurt small animals. As a businessman, Edison invented the light bulb just for promotion and to make more money.
When Tesla and the world prove the convenience of alternating current, Edison will take the lives of small animals to prove how dangerous Tesla said alternating current is. Edison told everyone that this kind of electricity will cause an explosion at any time, while direct current will not, so it is very safe.
Edison had such a great influence on Tesla that Tesla was always in a state of schizophrenia in his later years. Edison's view of capital is really terrible. It is hard to imagine that he would ruin another person's future for his own interests and reputation.
Although Edison has made our life more and more convenient, his mistakes cannot be covered up like this. Because of him, Tesla was ruined.
